Atlas - 40 000 443 - Locomotive, Diesel, EMD GP7 - Kansas City Southern - 4151

Model Information: The Atlas GP7, GP9 and GP9-TT models are some of their oldest models. The models share the same internal mechanisms and differ only in their shell details. Unlike many of their other older body styles, these bodies have been updated several times and are still a regular part of the Atlas production cycle.

The first release of this body type was in 1974 and the models were produced by Roco in Austria. Production for these models ended in 1982. The next release started in 1987 and the models were re-tooled by Kato in Japan for Atlas. The third version came out in 1995 and was made in China for Atlas and these engines were essentially a redo of the Kato mechanism. Finally, in 2006, a completely new mechanism was introduced and this 4th version is a split frame, dual-flywheel, slow-motor, modern engine. Furthermore, with the more recent releases, most road-names and numbers are available in both a DCC-Ready and a Decoder-Equipped version.

Assembly instructions from Atlas: GP7 (Japan version), GP7 Ph.1 (China version), GP7 Ph.2 (China version).

DCC Information: The first version of this engine (Roco) gets a solid "No" for DCC capability, but this is no surprise as these were made in 1974. The next two releases (Kato and China) are split-frame, but also split-board. They may be DCC-Friendly, but likely it will be a fair amount of work to upgrade these. The most recent version (China, 2006+) is eminently DCC-Ready. Furthermore, most road-names and numbers produced since 2006 are available in both a DCC-Ready and a Decoder-Equipped version. Earlier DCC factory-equipped versions were fitted with Lenz LE063XF decoders, whereas most recent versions are fitted with NCE N12A2 decoders. The Atlas version of these decoders will respond to manufacturer's address "127" (CV8) i.e. "Atlas Model Railroad Products", though being identical to their original manufacturer's specification.

For non-DCC-ready versions, a wired DCC decoder installation for this model can be found on Brad Myers' N-scale DCC decoder installs blog.

Models produced since 2006 accept the following plug-in decoders:
- Digitrax DN163A4: 1.5 Amp N Scale Board Replacement Mobile Decoder for Atlas GP30 and other short Atlas diesel locomotives.
- Digitrax DN163A2: Retired decoder, replaced by DN163A4.
- NCE N12A2: Plug and play decoder for N-Scale Atlas Classic Series GP7, GP9, GP30, GP35.
- TCS ASD4 (Installation for GP7, Installation for GP9)
- MRC 1955: N-Scale Sound Decoder for Atlas GP-7, GP-9, GP-30 or GP-35

Prototype History: The EMD GP7 is a four-axle (B-B) road switcher diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954. Power was provided by an EMD 567B 16-cylinder engine which generated 1,500 horsepower (1,119 kW). The GP7 was offered both with and without control cabs, and those built without control cabs were called a GP7B. Five GP7B's were built between March and April 1953. The GP7 was the first EMD road locomotive to use a hood unit design instead of a car-body design. This proved to be more efficient than the car body design as the hood unit cost less to build, was cheaper and easier to maintain, and had much better front and rear visibility for switching.

Of the 2,734 GP7's built, 2,620 were for American railroads (including 5 GP7B units built for the Atchison, Topeka and Santa Fe Railway), 112 were built for Canadian railroads, and 2 were built for Mexican railroads. This was the first model in EMD's GP (General Purpose) series of locomotives. Concurrently, EMD offered a six-axle (C-C) SD (Special Duty) locomotive, the SD7.

Road Name History: KCS began (with a different name) in 1890 under the direction of Arthur Stilwell for the purpose of building a railroad from Kansas City directly south along the Missouri – Kansas, Arkansas – Oklahoma, and Louisiana – Texas borders to the Gulf of Mexico. At the point where the railroad met the Gulf, Stillwell built a port complex and named it after himself, Port Arthur, Texas. Two years later, the company defaulted on a loan, Stilwell was kicked out and they changed the name of the railroad to Kansas City Southern. Stilwell went on to build the Kansas City Mexico & Orient.

The KCS steam fleet was, well, peculiar. They were the only railroad to use 0-6-6-0’s, not as heavy switchers, not as pushers, but as mainline road engines. 2-8-8-0’s were also used for heavy road service with Santa Fe types and Consolidations filling out the freight roster. 11 Pacifics handled the passenger trains. They were odd first in that they had 2 sand domes (rare on passenger power.) Second, they had a high mounted headlight but without a number plate in the middle of the smokebox door, giving the front a strange “faceless” appearance. A few of these Pacifics assigned to the Kansas City – Port Arthur “Flying Crow” were equipped with air horns that sounded like a cawing crow… Really! KCS also had 2 Shays used to muscle cars up and down the 10% grades of many Kansas City industrial spurs. (If you’ve been to Kansas City, you will understand why.) The pinnacle of the fleet was the J class 2-10-4’s, purchased to replace the 0-6-6-0’s in 1937. These were the last Texas types built by Lima and had sleek, jacketed boilers and enclosed cabs.

In 1939, the KCS acquired the Louisiana & Arkansas which ran from Dallas east to Shreveport and then New Orleans. Actually, it was the owners of the L&A that bought the KCS but for charter reasons, the deal was arranged so that KCS took control of L&A. L&A remained semi-autonomous in an SP-Cotton Belt sort of way. This brought the KCS system to over 1,660 miles (between Grand Trunk Western and Delaware & Hudson in relative size.) The L&A image began to fade away in the 1960s but it wasn’t fully merged into KCS until 1992.

Dieselization came primarily from EMD with E’s pulling the Flying Crow and Southern Belle, and F’s in freight service. These were delivered in the classic red, black and yellow with red being dominant on the freight units and yellow on the passenger units. A-B-B-A sets of Erie Builts were also used in freight service but were notorious for breaking knuckles on the hog-back hills of the Ozarks.

Switchers and first generation hood units were delivered in black with white trim (much like Illinois Central) with the name spelled out on the long hood. Hood units and switchers came from EMD, Alco, Baldwin and FM.

In the 1960s, the paint scheme was simplified to a solid red. This became known as Deramus Red after the line’s CEO William Deramus II. Deramus’s son (William III) was head of Chicago Great Western and later M-K-T, both of which used similar reds. While William II was a reasonably adept CEO, his son William III was less successful, at least as far as the railroad was concerned. Under William III, track deteriorated and customers fled, which in turn permitted him to cut more service and staff. Fewer, longer trains were dispatched. Meanwhile William III was pouring available cash into diversifying into less regulated industries. By the 1970s, KCS faced a triple threat. Track condition was at an all time low, the first generation diesels were wearing out and tonnage was increasing. A new CEO began to turn the railroad around. The red paint scheme was dumped for white with red lettering. Grain moving down from Kansas City was joined by petro-chemicals moving up from the coast. Powder River Coal joined the mix during this period.

KCS’s diversified holdings, including the Janus Fund, made KCS ripe for takeover. In 1985, leftist fundraiser George Soros attempted a hostile takeover but was foiled first by a real estate developer and then by a Deramus successor who had since moved to Hallmark Cards and then bought a large block of KCS stock.

Now a rousing success, KCS spun off Janus and other holdings and kept the railroad because that is where the REAL money was! In 2006, the Southern Belle red, yellow, and black paint scheme was re-introduced. A version of it was even applied to some new KCS freight cars (KCS freight cars had been notorious dull for decades with few having anything more than reporting marks to trumpet their owner.)

Brand/Importer Information: In 1924 Stephan Schaffan, Sr. founded the Atlas Tool Company in Newark, New Jersey. In 1933 his son, Stephan Schaffan, Jr., came to work for his father at the age of sixteen. Steve Jr. built model airplanes as a hobby and frequented a local hobby shop. Being an enterprising young man, he would often ask the owner if there was anything he could do to earn some extra spending money. Tired of listening to his requests, the hobby-store owner threw some model railroad track parts his way and said, "Here, see if you can improve on this".

In those days, railroad modelers had to assemble and build everything from scratch. Steve Jr. created a "switch kit" which sold so well, that the entire family worked on them in the basement at night, while doing business as usual in the machine shop during the day.

Subsequently, Steve Jr. engineered the stapling of rail to fiber track, along with inventing the first practical rail joiner and pre-assembled turnouts and flexible track. All of these products, and more, helped to popularize model railroading and assisted in the creation of a mass-market hobby. The budding entrepreneur quickly outgrew the limitations of a basement and small garage operation. Realizing they could actually make a living selling track and related products, Steve and his father had the first factory built in Hillside, New Jersey at 413 Florence Avenue in 1947. On September 30, 1949, the Atlas Tool Company was officially incorporated as a New Jersey company.

In 1985, Steve was honored posthumously for his inventions by the Model Railroad Industry Association and was inducted into the Model Railroad Industry Hall of Fame in Baltimore, Maryland. In addition, Steve was nominated and entered into the National Model Railroad Association Pioneers of Model Railroading in 1995.

In the early 1990s, the Atlas Tool Company changed its name to Atlas Model Railroad Company, Inc.
